VDP Manual Configuration
MAN_LINE_PGM, Enable Manual Line Programming of
VBI Standards, Address 0x64 [7], User Sub Map
The user can configure the VDP to decode different standards on
a line-to-line basis through manual line programming. For this,
the user must set the MAN_LINE_PGM bit and write to the
VBI_DATA_Px_Ny line programming bits (see Register 0x64
to Register 0x77 of the user sub map).
0 (default)—The VDP decodes default standards on lines as
shown in Table 66.
1—The VBI standards to be decoded are manually
programmed.
VBI_DATA_Px_Ny [3:0], VBI Standard to be Decoded on
Line x for PAL, Line y for NTSC, Addresses 0x64 to 0x77,
User Sub Map
These bits are related 4-bit clusters in Register 0x64 to Register 0x77
of the user sub map. The 4-bit line-programming registers, named
VBI_DATA_Px_Ny, identify the VBI data standard that would be
decoded on Line x in PAL mode or on Line y in NTSC mode. The
different types of VBI standards decoded by VBI_DATA_Px_Ny
are shown in Table 67. Note that the interpretation of its value
depends on whether the ADV7188 is in PAL or NTSC mode.
Notes
Full field detection (lines other than VBI lines) of
any standard can also be enabled by writing into the
VBI_DATA_P24_N22 [3:0] and VBI_DATA_P337_N285 [3:0]
bits. Therefore, if VBI_DATA_P24_N22 [3:0] is programmed
with any teletext standard, then teletext is decoded from
the entire odd field. The corresponding bits for the even
field are VBI_DATA_P337_N285 [3:0].
In teletext system identification, VDP assumes that if teletext
is present in a video channel, all the teletext lines comply with
a single standard system. Therefore, the line programming
using VBI_DATA_Px_Ny registers identifies whether the
data in line is teletext; the actual standard is identified
by the VDP_TTXT_TYPE_MAN bit. To program the
VDP_TTXT_TYPE_MAN bit, the VDP_TTXT_TYPE_
MAN_ENABLE bit must be set to 1.
